Abstract
Introduction:Arterial hypertension is a disease that has a high impact on cardiovascular mortality and morbidity; however, it is still insufficiently controlled.Objectives:To assess hypertension control in patients seen at a specialized clinic and to identify associated variables.Method:Cross-sectional study involving the analysis of medical records from 782 patients treated in a highly complex outpatient clinic. Inclusion criteria: age ≥18 years, diagnosed with hypertension, in treatment ≥6 months. Patients with secondary hypertension (104) and incomplete data (64) were excluded. The main outcome was blood pressure control (systolic <140 and diastolic <90 mmHg). The independent variables studied were: sociodemographic and clinical characteristics (use of drugs, comorbidities and laboratory tests). Pearson's χ2 tests, Fisher's test, Student's t and Wilcoxon-Mann-Whitney tests were performed in the bivariate analysis and logistic regression in the multiple analyses, adopting p≤0.05.Results:The prevalence of hypertensive control was 51.1%. It was associated with a lack of control: body mass index (OR = 1.038; 95% CI = 1.008 - 1.071), history of stroke (OR = 0.453; 95% CI = 0.245 - 0.821), left ventricular hypertrophy (OR = 1.765; 95% CI = 1.052 - 3.011), and number of medications (OR = 1.082; 95% CI = 1.033 - 1.136).Conclusion:About half of the hypertensive patients had their blood pressure controlled; clinical variables and target organ damage were associated with the control.
Highlights
Arterial hypertension is a disease that has a high impact on cardiovascular mortality and morbidity; it is still insufficiently controlled
We had 614 hypertensive patients participating in the study, half of whom (51.1%) had controlled blood pressure
Concerning a personal history, half of the hypertensive patients had a history of Dyslipidemia, and just over a third had diabetes mellitus, followed by chronic renal failure, obesity and resistant arterial hypertension
Summary
Arterial hypertension is a disease that has a high impact on cardiovascular mortality and morbidity; it is still insufficiently controlled. Objectives: To assess hypertension control in patients seen at a specialized clinic and to identify associated variables. Conclusion: About half of the hypertensive patients had their blood pressure controlled; clinical variables and target organ damage were associated with the control. Blood pressure control is the main goal of hypertension treatment and, when achieved, it reduces cardiovascular events[9]. Despite the benefits, achieving half the control of hypertensive patients is still a major challenge. This involves complex aspects, such as drug treatment compliance, which has particularities related to disease chronicity, access to healthcare services and the very biosocial characteristics of hypertensive patients. In a national systematic review, whose control rates ranged from 10% to 57.6%, only 24.4% of the publications analyzed hypertensive patients seen in secondary care centers[11]
